Question
Which one of the following fuels has the highest calorific value?A Hydrogen gas B LPG C CNG D Petrol
Solution
The fuel with the highest calorific value among the options given is A. Hydrogen gas.
Here's why:
-
Calorific value is the amount of energy produced by the complete combustion of a material or fuel. It is measured in units of energy per amount of material, typically kilograms or liters.
-
Hydrogen gas has the highest calorific value of any fuel. It produces about 142 MJ/kg. This is because hydrogen is the lightest element and it has the highest energy content per unit of weight.
-
LPG (Liquefied Petroleum Gas) has a calorific value of about 46 MJ/kg, CNG (Compressed Natural Gas) has a calorific value of about 55 MJ/kg, and Petrol has a calorific value of about 44 MJ/kg.
-
Therefore, among the options given, Hydrogen gas has the highest calorific value.
